With the Identity service you can perform two actions:

* Proof you are a unique, live individual and whitelist a new wallet address into the GoodDollar protocol by generating a unique Face Verification link.
* Query the status of a connected wallet in your dapp eg.:
  * Expiry Date
  * Verify a new wallet address is owned by a live and unique person.
  * If a person connected different wallets, the root whitelisted address can be retrieved

There are two SDK's available for builders to integrate the identity flow into their dapps:
